Thanks for your reply. I was sort of thinking along that line but had hoped that whatever SS06 uses could be found by the Ship Driver. However, thinking along, SS06 probably pre-ceded USB as well.
I have the newer SS08 and do enjoy it and am looking forward to some more programs. I'd like to drive a sub, but my version of a sub game is DOS. Yes, I've been around a long time...
I have the Rail Driver too and between the two, time permitting would only have to get called for meals.
It's not the case though as I do have house chores and gardens to tend. At 63, it's difficult to make choices, but with the world economies, garden sounds like more of a necessity right now.
Thanks again for the help.
